Marca got in touch with Alberto Asiaian, an expert at handwriting analysis. He observed these things about Cristiano Ronaldo’s signature and how they relate to his personality:

• upward slant = ambition and the drive to excel; “He is more motivated by professional success and recognition than big-money deals”
• the angle of the left-side of his autograph = he’s angy when he doesn’t win or score
• the way that he writes “Ronaldo” (overshadows his first name) suggests that he likes being admired by others for his professional efforts
• reserved; doesn’t like to talk about his personal life and will only discuss professional matters when necessary
• by the way his letters are joined together, he is friendly and extroverted (when he is the center of attention)
• the fluctuation of letter sizes = big ego
